Authentication Fails Trying to Send Mail via Google Apps SMTP from PHP

As you may know helgeklein.com also hosts a forum where I help people who have questions related to my software. The forum is configured to send out e-mails when new posts are added or when newly registered users need to confirm their e-mail addresses. Since I use Google Apps for helgeklein.com I configured Google’s SMTP server for outgoing e-mails. All worked well until recently when I started to wonder why I had not received new forum post e-mails for several days.
